Having dealt with a fair amount of MBTI/Socionics and some other pop psychology, I tend to be skeptical of these sort of typologies. It's why we are still dealing with "Alpha Wolf" BS. With roleplaying games, I find most of the player typologies, including more academic ones, tend to fall short of providing satisfying insight about players in one way or another IMHO.That's fair, and I agree! But that also ties into the "endless loop" that has been described by Torner, et al., in the hobby.
A. Amateur hobbyist declaring that there's a problem in TTRPGs.
B. This problem is caused by inconsistent desires/agendas/types of players.
C. Therefore, a new typology of players will be announced (almost always with some types being more equal than others, in the George Orwell sense).
D. Based on that typology, a theory (or theories) of TTRPGs and/or game design will bloom, under the concept that the system itself will enable/encourage/assist in certain types of play.
E. Rinse, repeat.
I think typologies of roleplaying games - game system "families" and common features they share - would be of greater value. Then layer the X Cultures of Gaming on top of that.
...as it was written in the The Elusive Shift by St. Peterson the Evangelist?In addition, because of the hobbyist nature, the past lessons keep getting forgotten. We just keep re-inventing the wheel.

Having not read The Elusive Shift yet, I can't really comment in full. I have no doubt that the hobby has been dancing around a lot of the same key underlying issues from the beginning. Likewise, I don't doubt that a lot of early lessons have been forgotten. I am not entirely sure if we are just re-inventing the wheel, even if we are dancing around those same issues. If we are, it's not without good reason, IMHO. Our hobby was changing, is changing, and will change again in response to demographic changes in our hobby and our surrounding culture. And the far greater reach and influence that video games and its theories will undoubtedly make on our hobby cannot be underestimated.A lot of debate that was once in zines moved to Usenet, then to forums, then to Google+ and since elsewhere across the net (e.g., Discord, Reddit, etc.). However, I suspect that a lot has been recontextualized over time. Call and response to past movements and the surrounding culture isn't exactly a new thing outside of roleplaying games. It's a pretty descriptive phenomenon when it comes to artistic and cultural movements as well. I tend to think that falling back on the phraseology of "just keep re-inventing the wheel" does a great disservice to this call and response of our hobby to itself and the wider culture.
